hi, need some advice. grace will not sleep during the day no matter what i try. also she does not like to be put down at all and is left for more than 2 minutes screams the place down. have spoken to hv who said she will slowly learn she cant be held all of the time but its getting me down. mark has no play time with me as grace takes up so much of my day. also marks feeding and nap has become rushed as grace is screaming if left. luckily mark is an angel and plays well on his own as well as going down for a nap easily.any ideas on what i can do?????
