Parenting in the toddler years is hard work!
Yes, being mostly positive and proactive parents, rather than negative and reactive ones, is more pleasant for toddler and mum, but both approaches are still hard work!
Do ensure you have time for yourself each day - a time to read, sew, chat to a friend, exercise or relax. Think creativley - even 20 minutes a day will help add balance to your day.
Also think about how you can get a morning or evening to yourself each week. Having a fun spot to look forward to each week can really help in those difficult moments. Maybe swap time with a friend so you each get a break, or take turns with your spouse.
Fun spots each day and each week can certainly be sanity savers during this intense season of parenting.
